a. a satin- 51 d ssin wirtijiivfej lvi'ininnfor Biiooktvi fwhw Yonki machines provisionis made rorbendin the reegs of tlre pins inwardly oreutwardly but tdetiiect thisit-' beconies "necessary to place on the machine *the 'particulaiforin off'clincher device desired ro used, and this obvieu'sly' reqnires rlre unecl-ianicar in terchzfimging of the" cline'her devices with the attendant nestle incident thereto and loss of use "oi" the machine during "the interim:

' To *avoid these-objections the resen t invention proposes 'to pre vitle air attachment so constructedand motinted en' the machine that by simple and quick operatiofl the inacliine may beset "to be'ntl the piicn s inwardly or outwardly, and this without in anywnamier rebdnstructiiig' the machine or appreciably altering its present arrange ment.

The duplex clincher devicedisclosed herein is designed with a special reference to the Soabar type of pin ticketing machine though it will be understood that the mechanism employed and its principle of operation are adapted to any type of pin attaching machine wherein the pins are capable of having their prongs bent inwardly or outwardly.

The invention is disclosed by way of 1llustration in the accompanying drawing,

wherein Figure 1 1s a slde elevational view showing the device installed on aSoabar pm ticketing machine;

Fig. 2' atop plan view thereof;

Fig. 8 a transverse sectional View taken on the line 33 of Fig, 1;

Fig. 4 a detail perspective view of the duplex clincher device per se;

Referring to the coiist'ructioir in further deter and f wherein "lilte' "*r Terence cliarac'f ters' de-simme corresponding part-s "in the different views shown, 9 represe itsfthebase or frame portion of the" So'abar machine 10 thein slide thereof; 11" the 1 bender ann 12 -t1ie ?lever-for o eratingi rbendeiaria-11; l3- the-"pin=clincher arfmf and14 the"lever iforf opei ting-said ariir.

The lever 12' *is' provided "with the usual bracket piece 15* -carrying sljl-iilg te'nsioned bolt 16= engag with the bifurcated member *17 1 that op'er tes thepi n bender arn'i -11; and with in the trough portion of said arm 11is fulcrtimedy'at18,the clincher arm 13;

Said pin-benderarm11 isi-n turntulcrume'd The du'pl'ex clincher device per se consists of a block'member 21 detachably secured to the endfportion 2213f" the bender arnrll' by the pair ofscrews"28, or'inany otherap provedmanner; Said bmck 2l='is recessed in its" upper portion; as 24a, to receive the fionge' of theWicket pi ns and "bendthe same inwardly after the manner of the special form of clincher for effecting this and with which the Soabar pin ticketing machine is equipped.

The block 21 carries the outward clincher I device in the form of a plate 25 centrally cut away (see Fig. 4:) and mounted to have limited movement within the pair of opposed slots 26 formed in opposite sides of the clincher block 21, as shown. A slot 2? formed in the lower end of the clincher member 25 receives the end member 28 oi the clincher arm and it is therebyoperated through the instrument of the pair of lev ers 12 and 14, as will be understood The means for shifting the duplex clincher device consists of an eccentric member 29 mounted on the stem 19 of the key 20 and fitting within a corresponding shaped opening formed in the fulcrum end of the pin bender arm 11. Said eccentric member and the key 20 are held against relative rotation by a pin 30 on the key stem 19 engaging within a slot 31 formed in the eccentric (Figs. 6 and 7). It will therefore be seen that by turning the key member 20 the respective clincher devices are moved into and out of operative position.

The locking device for holding the key 20 in set position consists of a latch piece 32 slidably fitted on the base portion 9 by the two screws, one acting as spring anchor, 33 engaging in slots 34:, of the latch piece, and a retraction spring 35 engaging the latch handle 36 normally holds the end 37 of the latch piece in locking engagement with the stem 19 of the key 20.

The operating lever 12 is provided with the usual adjusting and am nuts 38 and 39 for raising or lowering the pin bending arm; and in like manner the clincher operating lever 14 is fitted with adjusting nuts -10, as shown.

It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spirit of the invention, and, therefore, I do not wish to be limited to such features except as may be required by the claims.

What is claimed as new is:

1. In a pin attaching machine the combination of devices for applying pins having prongs, a duplex clincher adapted for movement in one direction to shift the clincher devices, and a member movable in another direction to carry the duplex clincher into operative position, substantially as set forth.

2. In a pin attaching machine the combination of means for applyingpins having prongs, a pair of clincher devices for bending the pin prongs inward or outward, an arm on which said clincher devices are mounted, and a device for shifting said arm to bring either of said clincher devices into operative position, substantially as set forth.

3. In a pin attaching machine the combination of means for applying pins having prongs, a pair of clincher devices for bending the pin prongs inward or outward, an arm on which said clincher devices are mounted, and an eccentric element for shifting said arm to bring either of said clincher devices into operative position, substantially as set forth.

4. In a pin attaching machine the com bination of means for applying pins having prongs, a pair of clincher devices for bending the pin prongs inward or outward, an arm on which said clincher devices are mounted, a device for shifting said arm to bring either of said clincher devices into operative position, and a locking element associated with said arm, substantially as set forth.

In a pin attaching machine the combination of means for applying pins having prongs, a block having elements for bending the pin prongs inward or outward, a fulcrumed arm on which said block is mounted, and an eccentric device for shifting the arm to bring either of the clincher devices of the block into operative position, substantially as set forth.

6. In a pin attaching machine the combination of means for applying pins having prongs, a block constructed to bend the pin prongs inward, a member slidably mounted on said block for bending the pin prongs outward, and devices for shifting the block and said slidable member into their respective operative positions, substantially as set forth.

In testimony whereof I aflix my signature.
